Abstract

PURPOSE: To enable more accurate velocity detection in a low velocity area to be conducted by using the newest latch data obtained when a CPU reads counted values in the low velocity area.
CONSTITUTION: A pulse generator 10 generates pulses of two phases A, B different from each other by a predetermined angle as a motor 7 rotates, and trigger signals are generated by a pulse processing circuit 20 correspondingly to the rise and fall of each pulse. Values counted by a timer counter are sequentially latched by a latch means 22-26 in response to the trigger signals. In a low velocity area, the newest latch data obtained when a CPU 18 reads data, and data earlier than the latch data by one cycle are used to calculate the velocity of an elevator. Therefore, the velocity of the elevator in the low velocity area can be accurately detected.
